IMPROVEMENT IN VALVES FOR STEAM-PUMPS.

The Schedule referred to in these Letters Patent andv makingrpart of the name.

To all whom 'it 'may concern: A

Be it known that I, JOHN V. V. BooRA'nM, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful ImprovementV in Valves for Steam-Pumps, Meters, and other purposes, of which the following is a full, clear, v'and exv act description, reference being had to the accompanying drawing forming part of this specication', and in which- Figure 1 represents a sectional view, taken longitudinally through theworking cylinder, of a meter with my improvement iny valves applied thereto;

Figure 2, a sectional view, ltaken transversely through said cylinder, ofthe one-half 'or portion thereof; and Y Figure 3, a view of the induction-valve and accompanying parts detached, in illustration of my improvement.

Similar letters of reference vindicate corresponding parts.

-My invention consists in a novel construction and A action or arrangement, relatively tol the ports or passages which it controls, in connection with a moving diaphragm or piston, by which it is operated, of' an induction-valve for communicating a reversed action to said diaphragm or piston.

Said invention is applicable, among other purposes or uses, to gas or duid-meters and steam-pumps; but it will suliice here to describe it as applied to a liquid meter, the operation being the same with diiierent actuating mediums.

It embraces, as its characteristic feature, a flexible valve of an elastic character, carried by a sliding bush which is free tov move in an outside guide or guides, having a passage or passages between it and the hub, which passages establish connection alternately between the inlet-opening controlled by the valve and the chambers or spaces on. opposite sides of the moving diaphragm orpiston that said valve serves to con` trol, accordingly as the sliding 'hub is shifted in opposite directions by said piston or knockers connected therewith, and the valveby such action made to suddenly spring at the close of the pistons strokes to opposite sides of its inlet or opening controlledby the valve.

An induction-valve thus constructed and operating in concert with a suitable eductiou-valve or valves secures a very/rapidLperfect, and easy action as regards its control and reversal of the incoming current in various'reciprooating apparatus or devices, and is automatic in 'its action,` requiring no valve-gear to Work it.A

' Referring to the accompanying drawing- A represents the working or measming-cylinderv of a recip coating piston-meter, for water or other liquids, B being its piston.

A exible diaphragm, fastened down on its edges and capable o f `playing in opposite directions, may be substituted for the piston."

C is an outside inlet water-chamber, to which the water is .freely admitted at all times, and from which it is passed by an inlet-opening or valve-passage, b, to the interior of a cylindrical or other hollow guide or guides, l), which establish` connection at opposite ends; that is, on reverse sides of the opening b, with the opposite ends of the cylinder A.,

This connection may be direct, as regards the one end of the cylinder, and by a passage, c, as regards the other.

Arranged within the guide or guides D, so as to be capable of' freely sliding therein, is a hub, E, oonstrncted to establish apassage or passages, d, through the guide D, as 'by wings e on the hub, which latter may be made in sections, united by a coupling, and carries-intermediately of its length, and around or outside of it, fory play to opposite sides oi' the opening'ba valve, F, made of any suitable dexible and elastic material.

This valve is primarily operated by the piston B or knockers f connected therewith, as said pistonapproaches the opposite ends of its` stroke, by said piston or its kno'ckers striking the opposite ends, alternately, of the sliding hub E, which `striking; action, however, does not immediately carry the valve F to opposite sides oi' the opening b;bnt, by reason 'of the flexible character lof said Valve and sealing of it by the water under pressure on its back in proximity to its outer edge, the main sliding stroke ofthe hub E simply acts to give a reversely-protruding action or configuration to the valve within its outsideedges, as represented in iig. '3; and it is only at 4the, very extreme motion ofthe hub that the valve, by its elastic character, springsover to the opposite side of the inlet l). This occurs suddenly at the termination of the pis` tons stroke, causing a quick reversal of the inlet water to the opposite end of the cylinder A, the direction in the flow being determined by the side oi' the opening l), against which the valve rests or is closed. v l

Of course a suitable eduction-valve or valves must be provided to relieve the piston B of the water on itsback when the incoming current is reversed, and an automatic arrangement which eleots this is shown in the drawing, inconnection with outlet-ports g g but as any suitable ednction-valve or valves may be employed for operation in combination; with the induction-valve F; and as the eduction-valve represen ted in the drawing is made the snbjeet of a separate apsliding valve-oamrier or hub E, forv action on it by a,

plication-for Letters Patent, it is unnecessary here to moving diaphragm or piston, substantially as herein describe the same. Set forth.

What is here claimed, and deslred to be secured by J. V. V. BOORAEM. Letters Patent, is'- The exible andelastie induction-valve F, arranged Witnesses: for operation in relation to the inlet-opening b and FRED. HAYNEs, passageskeonneoted therewith, in combination with the B. E. RABEAU.
